Hi Cristian,
Per my debug log, the CPU ID is actually DPDK current core ID on NXP ARM64 platform whose socket ID is always 0.

NACK.

This is incorrect, probably a misunderstanding: the params->cpu_id is already the CPU socket ID (passed as parameter), and not the core ID. For core ID, we typically use variable names as core_id or lcore_id, and never cpu_id.
